We've already got some terrible stuff already in the past few years;
The Host-book and film bombed
City of Bones-Again, bombed
Beautiful creatures-again bombed
On the other hand, they were more direct spinoffs of Twilight or had Twilight's influence (the Host was by Meyer herself, and City of Bones was by a fan of hers)
The biggest Young Adult thing now is the Hunger Games, which, while I consider it a complete bore and quite terrible in its own right, doesn't have quite the impact or the sheer awfulness of Twilight
My question is, while that the Twilight series has been successful despite being hated by everyone with a brain, can this happen again? I know terrible books have had big followings like Gone With the Wind or Wuthering Heights and such, but I wouldn't call it the same phenomenon.
I guess what I'm asking is whether Twilight is just another a bad franchise and part of a larger cultural pattern (which would predict that this will continue to happen while the cultural paradigm exists), or if it was something especially unique, and if the latter is true, can it happen again?
